If the agricultural vehicle is in trouble during use, or if there is a fault and there is no spare parts supply and urgent use, some simple emergency methods can be adopted. Damage to the fuel tank can wipe the oil spill clean, apply soap or chewing gum to the oil spill and temporarily block it. Repair with epoxy adhesive, better results. Rupture of the tubing can wipe the cracked area clean, apply soap, wrap it with a piece of cloth or tape around the broken tubing, and tie it with wire, then apply a layer of soap. When the tubing breaks, it can find a rubber or plastic tube that fits the diameter of the tubing. If the socket is not tight enough, tie the wires tightly at both ends to prevent oil leakage. Car leakage can be based on the size of the trachoma, use the appropriate size of the electrical fuse, the hammer gently into the trachoma, you can eliminate oil leakage, leakage. Joint leakage is generally caused by the tubing bell mouth and the tubing nut being not sealed. The cotton yarn can be used to wrap around the lower edge of the horn and tighten the tubing nut and tubing connector. The bubble gum or maltose can also be chewed into a paste, coated on the tubing nut seat and allowed to dry to seal. The collapse of the precipitation cup can use tape or plastic tube to put the sediment cup into and out of the oil tube so that the oil does not pass through the sediment cup. Incoming and outgoing water hoses can be broken. If not, use a cloth coated with soap to wrap the leaks. If the cracks are large, cut the hoses to break them. Put a bamboo tube or iron tube in the middle and tie it tightly with iron wire.
